I a licaubn'aug ust 2E1, 1927. Serial No. 215,872 I '6 Claims. -(c1. 118 59 r The present invention relates to, a new-{andimproved lubricatingland guiding means for spinningmachines. i

More particularly the invention relates toiim ,5 proved lubricating and guiding means for travellers utilized in well known types of spinning machines for the production of twisted threads used in the manufacture of cth,-fabrics, and the like.

In the present commonly used'spinning machines for the twisting of silk and like thread, the threads tobe twisted are guided from spools oven rotating travellers, twisted into single strands and wound on bobbins. These travellers rotate against a metallic surface at high speed, and consequently ordinarily wear rapidly, thus requiring frequent replacements. In order to lubricate the travellers, as at present used, it is the practice to apply lubricant approximately twice 'a. day in a manner resulting in a considerable waste of lubricant and labor. The common manner of application of lubricant is such that excess lubricant finds its way up on the thread guiding sections of the travellers, discoloring the thread.

In operation of silk spinning machines, kinks frequently form in the twisted threadsand-lay over on the surfaces to which the lubricant for the traveller has been provided as the bobbins,

3 stop, absorbing oil and further discoloring the twisted'thread. The present manner-of apply ing the lubricant is inefilcient and only a small percentage of the lubricant used actually reaches the'traveller with the result'that the life of the travellers with the prior arrangements is about three days. The discolorations caused by the lubricant are almost impossible to remove from the twisted threads, thus making the weaving,

of light shades of fabrics and cloth from threads spun by the prior machines, a difficult and costly operation, as heavy losses occur due to the amount of goods which is damaged and which must be dyed dark in color so that the discolorations will not be visible. Accordingly,-a primary object of'our' invention is to provide novel guiding and lubricating means for travellers'in spinning mechanisms which are of such nature that the threads are protected from discoloration and a proper amount of lubricant with a minimum of labor is automatically applied to 3 the travellers. In practice the application of. our invention to standard spinning machines has materially extended the life-of the travellers without the necessity of frequent applicationof lubricant the application of' about fifteen. drops a of oil about once a month providing ample.lubricant,

materially increasing the life of the spinner, and substantially reducing the cost of lubrication and maintenance. Atthe same time, no 66 excess lubricant is present and the travellersree main free of oil as well as the exposed. surface of the lubricating ring thus making it impossible for kinks the thread to come into contact with any lubricant. With our improved device, it has become possible to spin purewhite threads without discoloration due to lubricant, making the production of pure white and the light shades ot'high grade silks, and other cloths, readily possible. 7 w

I

. Adapted to be supported onjthe outer surface 190 of ,the ring holder llcis a-- lubricating pan l4 whichcomprises a'base portion 15 equal in width to that of the ring holder and outwardly projecting annular inner and outer walls, 16 and 17 respectively. Adapted to seat on the outer flange :17 of the lubricating pan 14 is a ring which as' more clearly shown in Figure 2 is inwardly dished, "that is, the inner edge .of the ring is in pazplane. belowthart of. the'o'uter edge thereof The three members aboveitdescribed comprise 1 10 our improved guiding and lubricating device and fiangel'? and the inner edge thereof in spaced relation to the inner wall 16 defining an annular opening 19.

In Figure 6 is shown the application of our invention to a well known form of spinning machine comprising the traversing bar 21 provided i with openings 22 to which bar the guiding and" lubricating devices are secured in. register with the openings 22 by means of bolts 23 extending through the bar and slotted lugs 12 of the ring holders 11. a

Disposed beneaththe openings 22 inthe tration from thezframe of the machine and are rotated at a high speed by the driving belt 25.

Bobbins 26 uponwhich thetwisted thread is to be wound are supported on the spindles and rotated by pulleys 24 at high speed.

The threads 27 to be twisted and wound-on the bobbins 26. are fed from suitably supported rollers 28 through the wire loops 29 and are then passed around the corresponding vtravellers 30 to the bobbins 26 as indicated.

. 1As isv well known, in operationof devices of this character, the rotation. of, the bobbinsv and the action of thethreads 27'causesrotation of the traveller 30 twisting the threads into a single strand which is wound on the bobbins.-:- As the rotation of the ibobbins and the windingof the twisted thread proceeds; the traversing .bar 21 is reciprocated vertically causingthe winding of the twisted thread on'the bobbins. in uniform 1 l l In prior spinning travellers engaged and were guided by a metallic member in the form of a metallic ring and it has been the practice to applylubricant on the upper surface of suchring to lubricate theQtr'avellers.

As a result of this methodlof applying lubricant,

excess lubricant finds it way over the ends of the travellers to the thread guiding sectionsthereof and discolors the thread. Furthermore, when the spindles on which the bobbins; are supported stop, kinks form in the twisted thread due to the movement of theltraversing bar and frequently lay over on'the upper surfa'cesiof the. rings absorbing the oil and causing additional discoloration' of the thread. In accordance with our improvement herein disclosed, a small amount of lubricant iszsupplied in the pan l i, which as shown is'di'sposed beneath the ring. 18, the inwardly projecting portions of thetravellers extend within'the annular opening 19 and the ends thereof inoperation engage the innersu rfa ce of thering- As is well knownga' spinning machine isstopped several times aday at which time the travellers fall away from engagement with the under sur faces of the rings and the ends thereof will dip into the' lubricant in the pan 14. .When the machine is again put into operation the under surfaces of the ringswill belubricated by. means' of the lubricant carried by the endseof. the travellers; while .at the same time there is no possibility of any lubricant reaching thethread guiding sections of 'the travellers or the outer surfaces ofthe'ring. j

machines the ad; of the Thus in accordance with our invention, a small amount of lubricant, in practice about fifteen drops once a month, is supplied to the pan 14 after which the lubrication of the travellers need be given no attention and the usual operations of spinning can proceedwithout any possible danger of discolorationsin the thread due. to the lubricant. i What is claimed and U; S; Letters Patent is:
